MENETELMA LAAKEAINEENA KAYTTOKELPOISEN DIFENYYLIMETAANIJOHDAN-NAISEN VALMISTAMISEKSI
Ihmisen vakavimpia sairauksia nykyåån ovat akuutit verisuoni-sairaudet, kuten sydånlihasinfarkti, aivohalvaus, aivotukos, aivoinfarkti, keuhkotukos, syvå laskimotukos ja ååreisvaltimo-tukos.
Nykyaan hiutaloitumisenestoaineet ovat tulleet yleiseen tietou-teen ja niitå on kliinisesti kSytetty naiden sairauksien hoi-tamiseen. Niiden kSytto on kuitenkin ymmårretty vasta viime aikoina. Niinpå on odotettavissa, etta tulevaisuudessa kehite-taan parempia laakkeita.
Keksinnon mukaisella menetelmalla valmistetaan difenyylime-taanijohdannaisia, joilla voidaan hoitaa veren virtaushåirioi-den aiheuttamia sairauksia antamalla edella mainittua yhdistet-ta tax sen farmseuttisesti sopivaa suolaa.
Taman keksinndn mukaisella menetelmalla valmistetaan difenyyli-metaanijohdannainen tai sen farmaseuttisesti sopiva suola, joka on seuraavan yleiskaavan (I) mukainen: R1 R2 (I) li c jossa R1 ja Rz ovat hydroksyyli tai alempi alkoksi, X on syano ja Y on -(CH2)„-COOR3, jossa R3 on vety tai alempi alkyyli/ ja n on 1, 2 tai 3.

Alkoksiryhma mainittuna ryhmien RI ja R2 yhteydessa kasittåa minkå tahansa alemman alkoksiryhmån, joka saadaan edellå vii-tatuista alempi alkyyliryhmistå. Nåiden ryhmien joukossa me-tyyli- ja etyyliryhmåt ovat toivotuimpia alempi alkyyliryhmiå, kun taas metoksiryhmå on toivotuin alempi alkoksiryhma.
Kun R3 on vetyatomi voidaan tavoiteyhdiste muuttaa farmaseutti-sesti sopivaksi suolakseen, joka kasittåa metallisuolat, kuten Na-, K-, Ca- ja Mg-suolat.
